Extraction of uranium from solid waste containing uranium

Jun 01 2014 · Fig. 1 shows the points in the uranium conversion process where spent NaF adsorbents sludge-like wastes and residue wastes are generated. UF 4 was produced from a solution in which yellow cake was dissolved as uranous ions in a reaction bath. A portion of UF 4 which could not be transported because of solidification remained as a blockish residue waste in the reaction bath.
